Abstract
PURPOSE This article is the second in a two-part series aimed at exploring the spectrum of supratentorial intraventricular masses in children. In particular, this part delves into masses originating from cells of the ventricular lining, those within the septum pellucidum, and brain parenchyma cells extending into the ventricles. The aim of this series is to offer a comprehensive understanding of these supratentorial intraventricular masses, encompassing their primary clinical findings and histological definitions. METHODS We conducted a review and analysis of relevant epidemiological data, the current genetics/molecular classifications as per the fifth edition of the World Health Organization (WHO) Classification of Tumors of the Central Nervous System (WHO CNS5), and imaging findings. Each supratentorial intraventricular mass was individually evaluated, with a detailed discussion on its clinical and histological features. RESULTS This article covers a range of supratentorial intraventricular masses observed in children. These include colloid cysts, subependymal giant cell astrocytomas, ependymomas, gangliogliomas, myxoid glioneuronal tumors, central neurocytomas, high-grade gliomas, pilocytic astrocytomas, cavernous malformations, and other embryonal tumors. Each mass type is characterized both clinically and histologically, offering an in-depth review of their individual imaging characteristics. CONCLUSION The WHO CNS5 introduces notable changes, emphasizing the vital importance of molecular diagnostics in classifying pediatric central nervous system tumors. These foundational shifts have significant potential to impact management strategies and, as a result, the outcomes of intraventricular masses in children.

Abstract
Benign glioma broadly refers to a heterogeneous group of slow-growing glial tumors with low proliferative rates and a more indolent clinical course. These tumors may also be described as "low-grade" glioma (LGG) and are classified as WHO grade I or II lesions according to the Classification of Tumors of the Central Nervous System (CNS) (Louis et al. in Acta Neuropathol 114:97-109, 2007). Advances in molecular genetics have improved understanding of glioma tumorigenesis, leading to the identification of common mutation profiles with significant treatment and prognostic implications. The most recent WHO 2016 classification system has introduced several notable changes in the way that gliomas are diagnosed, with a new emphasis on molecular features as key factors in differentiation (Wesseling and Capper in Neuropathol Appl Neurobiol 44:139-150, 2018). Benign gliomas have a predilection for younger patients and are among the most frequently diagnosed tumors in children and young adults (Ostrom et al. in Neuro Oncol 22:iv1-iv96, 2020). These tumors can be separated into two clinically distinct subgroups. The first group is of focal, well-circumscribed lesions that notably are not associated with an increased risk of malignant transformation. Primarily diagnosed in pediatric patients, these WHO grade I tumors may be cured with surgical resection alone (Sturm et al. in J Clin Oncol 35:2370-2377, 2017). Recurrence rates are low, and the prognosis for these patients is excellent (Ostrom et al. in Neuro Oncol 22:iv1-iv96, 2020). Diffuse gliomas are WHO grade II lesions with a more infiltrative pattern of growth and high propensity for recurrence. These tumors are primarily diagnosed in young adult patients, and classically present with seizures (Pallud et al. Brain 137:449-462, 2014). The term "benign" is a misnomer in many cases, as the natural history of these tumors is with malignant transformation and recurrence as grade III or grade IV tumors (Jooma et al. in J Neurosurg 14:356-363, 2019). For all LGG, surgery with maximal safe resection is the treatment of choice for both primary and recurrent tumors. The goal of surgery should be for gross total resection (GTR), as complete tumor removal is associated with higher rates of tumor control and seizure freedom. Chemotherapy and radiation therapy (RT), while not typically a component of first-line treatment in most cases, may be employed as adjunctive therapy in high-risk or recurrent tumors and in some select cases. The prognosis of benign gliomas varies widely; non-infiltrative tumor subtypes generally have an excellent prognosis, while diffusely infiltrative tumors, although slow-growing, are eventually fatal (Sturm et al. in J Clin Oncol 35:2370-2377, 2017). This chapter reviews the shared and unique individual features of the benign glioma including diffuse glioma, pilocytic astrocytoma and pilomyxoid astrocytoma (PMA), subependymal giant cell astrocytoma (SEGA), pleomorphic xanthoastrocytoma (PXA), subependymoma (SE), angiocentric glioma (AG), and chordoid glioma (CG). Also discussed is ganglioglioma (GG), a mixed neuronal-glial tumor that represents a notable diagnosis in the differential for other LGG (Wesseling and Capper 2018). Ependymomas of the brain and spinal cord, including major histologic subtypes, are discussed in other chapters.

Diagnosis and Therapeutic Management of Ventricular Gangliogliomas: An Illustrated Review. World Neurosurg 2021; 149:e651-e663. [PMID: 33548530 DOI: 10.1016/j.wneu.2021.01.119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2020] [Revised: 01/22/2021] [Accepted: 01/23/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND Gangliogliomas (GGs) are extremely rare benign neoplasms frequently located within the temporal lobe that usually present with seizures. GGs growing predominantly within the ventricular system (VGGs) are even more infrequent, so definite conclusions concerning their diagnosis and therapeutic management are lacking. METHODS A retrospective review of case reports of VGGs was performed from the introduction of modern imaging techniques, including 4 new illustrative cases treated in our department. RESULTS Thirty-four cases were collected. Ages ranged from 10 to 71 years (mean, 26.62 years), and 55.9% were male. Most patients developed symptoms related to high intracranial pressure. The lateral ventricles were predominantly involved (58.8%). Obstructive hydrocephalus was observed in 54.5% of patients. Cystic degeneration and calcification were frequently observed. Surgical treatment was carried out in all cases. Morbidity and mortality were 17.6% and 2.9%, respectively. Gross total tumor resection was achieved in 64.5% of patients. Four patients experienced tumor dissemination along the neural axis. More than 90% of patients maintained a good functional status at last follow-up. CONCLUSIONS Despite their low incidence, a diagnosis of VGGs should be considered in young male adults who progressively develop intracranial hypertension, caused by a ventricular mass showing signs of cystic degeneration and calcification. Maximal and safe surgical resection represents the gold standard for the treatment of symptomatic VGGs, although total removal is frequently precluded by difficulties in defining appropriate tumor boundaries. Adjuvant radiotherapy should be considered if an incomplete resection was carried out, especially in World Health Organization grade III neoplasms.

Abstract
Abstract
Infratentorial glioneuronal neoplasms are overall quite rare and are more commonly low-grade with surgical excision usually being curative. Multiple distinct histologic entities have been described including rosette-forming glioneuronal tumor, papillary glioneuronal tumor, neurocytoma, dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease), cerebellar liponeurocytoma, and ganglioglioma. While each of these entities has distinct findings, in some instances a tumor may demonstrate overlapping histologic features with mixed components. Herein, we report 2 unusual adult cases of a fourth ventricular glioneuronal tumor with features of ganglioglioma and neurocytoma, with one coming from a surgical resection and one found incidentally at autopsy. To the best of our knowledge, this specific histologic combination has not previously been described. As such, the clinical significance is unknown although in both cases the neoplasms were circumscribed and appeared to be low grade. The presence of the gangliogliomatous component was of particular interest since these are extremely rare occurrences in the fourth ventricle and we provide a comprehensive review of infratentorial gangliogliomas.

Abstract
BACKGROUND Gangliogliomas are low-grade neoplasms that typically affect patients under the age of 30 and present with epilepsy and symptoms of mass effect. Here, we report a case of an intraventricular ganglioglioma involving the septum pellucidum in a pediatric patient with history of optic glioma. Only one other pediatric intraventricular ganglioglioma arising from the septum pellucidum has been reported previously. CASE REPORT The patient initially presented at 9 months of age with a pilocytic astrocytoma centered on the optic chiasm, treated with chemotherapy and radiation at 3 years of age. Routine follow-up imaging at 13 years of age revealed the development of a mass in the septum pellucidum, which was subtotally resected endoscopically because of its proximity to the fornices. Pathology confirmed a ganglioglioma positive for the BRAF V600E mutation. The tumor residual progressed and was treated with stereotactic radiosurgery. The patient was asymptomatic at her 6-month follow-up visit and the size of the nodule remained stable. LITERATURE REVIEW Our review of the 25 previously reported intraventricular gangliogliomas found that their pre-surgical diagnoses were often incorrect, reflecting the difficulty of making the diagnosis with signs, symptoms, and imaging alone. Patients can be reassured that the prognosis is generally favorable following uncomplicated neurosurgical resection.

Abstract
INTRODUCTION Ganglioglioma is a generally benign tumor, mostly occurring in patients <30 years old. Temporal lobe is most frequently involved. Up to now, only 3 cases were reported of ganglioglioma in the pituitary gland, all being confined to the neurohypophysis. Here, we are the first to report an adenohypophysis ganglioglioma. CASE PRESENTATION A 43-year-old woman presented with chronic headache was referred to our hospital. Magnetic resonance imaging (MRI) indicated pituitary adenoma. Endoscopic transnasal transsphenoidal surgery was performed. The tumor was rich in blood supply, with tough texture, therefore only subtotal resection was conducted. Pathology analysis revealed an adenohypophysial tumor composed of dysplastic ganglion cells and neoplastic glial cells collided with nonspecific hyperplasia of pituitary cells. Immunohistochemistry revealed positive staining of synaptophysin, glial-fibrillary acidic protein, and CD34. The results were consistent with the diagnosis of ganglioglioma. After the surgery the patient recovered well except developing cerebrospinal fluid rhinorrhea, which was controlled by lumbar drainage. MRI 6 months later did not show any sign of progression. CONCLUSION According to the findings of our case, concerns should be raised considering ganglioglioma as a differential diagnosis of mass located in the sellar region. Furthermore, an ideal management strategy for pituitary ganglioglioma is not known; therefore, more cases and long-term follow-up are needed to enrich our knowledge of the diagnosis, treatment, and prognosis of this rare intracranial lesion.
